Species-specific biological data are commonly combined with fishery operational data to model exploited stocks and determine appropriate levels of exploitation. However, this approach to fishery management is predicated on the ability of fishery data collectors to correctly identify exploited species. Sharks and other elasmobranch fishes (Elasmobranchii) can be particularly difficult to identify in the field, due to the close physical similarity to other species and/or a lack of taxonomic resolution in some lineages. This paper provides an overview of the difficulties surrounding the field identification of a number of elasmobranch species found in the Arabian/Persian Gulf, where they are heavily exploited and in urgent need of careful management.

对海湾鳗鱼渔业有效管理的潜在分类障碍的审查

特定物种的生物数据通常与渔业运营数据结合起来，以对开发的种群进行建模并确定适当的开发水平。然而，这种渔业管理方法取决于渔业数据收集者正确识别开发物种的能力。由于与其他物种的物理相似性和/或某些谱系缺乏分类学分辨率，鲨鱼和其他硬鳃鱼类 (Elasmobranchii) 在野外特别难以识别。本文概述了在阿拉伯/波斯湾发现的一些硬鳃类物种的实地鉴定困难，这些物种在那里被大量开发，急需谨慎管理。
